To whom t may concern:

Be it known that I, OSCAR S. TEALE, a citizen of the United States of America, and a resident of the city of Bloomfield, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Retouching-Machines, of which the following is a specification.

This invention relates to hand controlled and power driven instruments for retouching photographs and negatives, prints and pictures, etc. u

The instrument comprises a casing, preferably cylindrical, adapted to be manuall operated; a two part device shaft longitudinally adjustable, one section of which extends through the upper end of the casing and is adapted to be connected rto a suitable source of power; a pencil or stylus carrying shaftextending beyond the lower end of the casing and provided with a universal journal working in a bearingk fixedly held in the casing; a bearing in the upper part of the casing in which the outer section of the drive shaft is fitted to rotate Without end or axial play; a bearing similarly controlling the inner section of said shaft and fitted 1n the different angular positions to the axis of the drive shaft, causing its ends to revolve around the axis with the universal .bearing as an immovable center.

An essential rfeature of the invention, to`

insure accuracy and freedom of action of the working parts, is that all of mam bearings inthe casing are coaxial. Other novel features` reside in the special construction of the various devices, especially the pencil shaft controlling means and the bearings; all of which will now be fully described by reference had to the accompanying drawings, in which Figure 1 is a longitudinal section of a retouching instrument embodying the features of this invention. f

Fig. 2 is a view taken at right angles to Fig. 1, showin the central position of the instrument wit the casing removed.

Figs. 3, 4 and 5 are transverse sectional views on the lines 3 3, 4 4 and 5--5, Fig. 1, respectively.

The casing consists of a central part 6, an upper cap'7, and a lower conical section 8, the adjacent ends of the three parts being internally screw-threaded. The shell 9, of the upperibearingscrews into the thread of the top of the part 6, and the cap?, screws over the upper half of said shell 9; similarly the lower universal bearing 10, is screwed into the lower end of therpart 6, and the conical section 8 is screwed over the part of said bearing projecting beyond the end of part 6; thus the parts 9 and 10 of the upper and lower bearings constitute parts of the casing, whereby the three sections 6, 7 and 8 are rigidly heldtogether.y j y The upper section 11 of the drive shaft, to which a source of power may be connected by a flexible shaft in the usual manner, is formed with a circumferential groove 12, preferably concaved, into which fits a bearing ring, 13, diametrically divided and formed to seat in the shell 9, and held firmly -.in position by screws 14. ySaid shaft while free to rotate is held longitudinally stationary. The journal of the lower section 15, consists of opposed conical faces 16, which seat in corresponding bearing faces in the divided bearing 17, which is firmly held in the shell 18 by screws 19. This bearing is controlled and axially adjusted by being connected to the manipulating sleeve 20, by bars 21', secured at their upper ends to the shell 18', by the screws 19, and attached to the sleeve 20, by their rectangular hands 22 at their ends which pass through slots in rthe casing and into holes in said sleeve. In an axial socket 23 at the top of section 15, fits the inner end of section 11, of the drive shaft,

lsaid inner end being provided with a key or feather 24 fitted to slide in a slot formed in one side of the socket, whereby the two sections of the shaft are carried to rotate together under all axial adjustments..

a The universal bearing 10, is longitudinally divided, vthe two parts being held together at the upper ends by a ring 23, secured thereto by screws. bearing is tapered, corresponding to the taper of the lower section 8 of the casing, which by seating on the taper part of said bearing, when the bearing and the sections of the cas- The lower part of the` CAI ing are assembled, also assists in holding the two halves of the bearing together. This bearing has a central spherical cavity 2l, in which works the spherical ournal 25, rigidly secured to or forming part of the pencil carrying shaft 26, which is hollow for the reception of the pencil or stylus and is provided at its lower end with an ordinary clamping chuck QT.

The adjustable means for imparting motion from the shaft l5, to the shaft 26, from a simple rotary motion, when the axis of said shaft 2G, is coincident with the axis of the main bearings, to increasing circular movements of the axis of shaft- 2G, around said main axis, with a stationary point at the center of the universal bearing, consists of a hollow head 28, at the lower end of shaft l5, having inclined slots 29, in theopposed walls, and a crosshead or lugs 30 projecting from the flattened end of the solid part Sl of the shaft 26; the arrangement being such that, the crosshead 30 fitting in the slots 29, the shaft l5 with its head Q8, may by means of the sleeve 2O and its associated devices be set to locate the axis of shaft 26 coincidently with the main axis of the instrument or moved into angular Jositions relatively thereto, so that as said head rotates the upper end of the axis of shaft 26, will move in circles of varying dimensions and the point of the pencil or stylus be carried to correspondingly inscribe or mark circles by moving in the opposite direction, Holding the instrument stationary over the photograph or other obj ect to be retouched circular markings of various sizes may be produced; if the instrument be moved over the object overlapping circular or scroll like markings will result.

It is evident that the instrument may be used in dot and straight line retouching work, as an ordinary pencil or stylus, by setting the shaft 2G, on the axis of the bearings. The point of the pencil or stylus will of course rotate if the source of power is not cut off, but such movement need not militate against handling of the stylus for line or dot work.

I claim:

l. A retouching instrument, comprising a casing, a drive shaft extending from and having bearings at one end of the casing, a pencil or stylus carrying shaft extending` from the other end of the casing and provided with a universal journal, a bearing` for said journal tixedly held in the casingl coaxially with the drive shaft bearings, a radially adjustable connection between the adjacent ends of the shafts, a sleeve slidable on the casing near its stylus carrying end, and bars extending lengthwise the casing and connecting said sleeve with the inner bearing of the drive shaft.

Q. A retouching instrument, comprising a casing consistingof a central section, a cap at one end, similarly internally screw threaded, a bearing shell fitted in the central section, as a bushing to hold them together and a conical end section secured to the other end of the cent al section, a drive shaft extending from and having bearings at one end of the easing, one of said bearings being held in the shell connecting the centralisection and cap, a pencil or stylus carrying shaft extending from the other end of the easing and an adjustable coimection between the drive shaft and pencil carrying shaft.

3. retouehing instrument, comprising a. casing consisting a central section, a cap at one end, similarly internally screw threaded, a bearing shell fitted in the central section, as a bushing to hold them togetlier and a conical end section secured to the other end of the central section by a peripherally screw threaded bearing seated in them, a drive shaft extending from and having bearings at one end. of the easing, one of said bearing being held in the shell connecting the central section and cap, a pencil or stylus carrying shaft extending from the other end of the casing` and provided with a universal journal working in said bearing and an adjustable connection between the drive shaft and pencil carrying shaft.
